福島第一原発
福島第一原発1号機と3号機が爆発に至るまでの説明の中の一文です。
ベントが行われたが、格納容器内に充満していた水素、可燃性ガス、粉塵が排気ルートである原子炉建屋内３階のフィルター集中し、粉塵で目詰まりを起こす。
Thanks in advance.

ここで言う粉塵とは次のリンクで説明されている airborne particulate matter のことです。一般的には particules と表現すれば十分だと思います。

補足的情報ですが、原子炉のcontainment ventilation system にはこの粉塵が大気に放出するのを防ぐ high-efficiency particulate air (HEPA) filter が装備されていると言われています。

“Some emergency situations, however, require venting directly from the drywell to reduce the pressure. This also happened at Fukushima. If the RHR system were operating and could spray water into the drywell, this water would help remove radioactive particles and gases from the containment atmosphere, preventing this material from being released to the environment during venting.”

2) I would prefer to translate 粉塵 as "radioactive dust". Although the sentence does not expressly state that that 粉塵 is radioactive, it is implied.
